IMPROVEMENT IN COMPOU OF OAKLAND, CALIFORNIA.

ND FOR ARTIFICIAL STONE.

Specification forming part of Letters Patent No. 185.551, dated December19, 1876; application filed November 28, 1876.

To all whom it may concern:

Be it known that I, LLEWELLYN L. LEATH- ERS, of Oakland, Alameda.county, State of California, have invented an Improved Artificial Stone;and I do hereby declare the following description is suflicient toenable any person skilled in the art or science to which it most nearlyappertains to make and use my said invent-ion without further inventionor experiment.

My invention relates to a novel combination of materials for compoundingand producing an artificial stone of great and superior strength,durability, and hardness at a slight expense for material.

To make my artificial stone, I first make a chemical liquid or compoundin the following manner: I first dissolve two and one-half pounds(apothecaries weight) of borax in thirty quarts of water then dissolveone and one-fourth pound Iapothecaries weight) of kaolin in thirtyquarts of water then dissolve pound apothecaries weight) of sul )hur inthirty q uarts of alcohol. When tide Wingredients are thoroug y andseparately dissolved, as stated, I mix the SGV6I& I Ql tLt i Q Q orcompounds by pouring them together into well mixed while dry four partsof clean sili- W p U bed with thirty gallons of' water "anarttattii mmix, and then use a suficient quantity of said lastmentioned dilutedmixture to dampen "said mixed sand matemgggst that it can be m vc"firtntsiatway. I am thus able to produce an artificial stone of greatdurability and superior hardness.

N. B. The stone, after being manufactured as above stated, should bekept dampened with water for about four days, in which time it willpetrify and harden fit for use.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The process above described for making a chemical mixture orcompound, diluted as and for the purposes set forth.

2. An artificial stone composed of sand and cement, moistened with achemical mixture or compound, diluted, as above described, beforetamping, substantially as and for the purposes above set forth.
